Abstract: A novel heterotricyclic compounds of Formula 1 or pharmaceutically acceptable salts thereof, and uses thereof are disclosed. The novel heterotricyclic compounds exhibit an inhibitory activity against EZH1 (enhancer of zeste homolog 1) and/or EZH2 (enhancer of zeste homolog 2) activity. Pharmaceutical compositions containing these compounds as active ingredient is also disclosed. The heterotricyclic compound, pharmaceutically acceptable salts thereof, or compositions containing the compound or salt are useful in treating tumor or cancer in a subject.

Abstract: Disclosed are novel dioxoisoquinolinone derivative compounds, pharmaceutically acceptable salts thereof, optical isomers, hydrates, and solvates thereof as well as uses thereof. More specifically, the novel dioxoisoquinolinone derivative compounds, pharmaceutically acceptable salts, optical isomers, hydrates, solvates show inhibition activity of EZH1 (Enhancer of zeste homolog 1) and/or EZH2 (Enhancer of zeste homolog 2) activity. Pharmaceutical compositions containing the compound is also disclosed.
